' BOOK COVER.

Application filed. July 28, 1928.

To all whom it may concern:

Be it known that I, JoHN Sermon, a citizen of the United States,residing at the city of Holyoke, in the county of Hampden and State ofMassachusetts, have invented certain new and useful Improvements in BookCovers; and I do declare the following to be a full, clear, and exactdescription of the invention, such as, will enable others skilled in theart to which it appertains to make and use the same.

This invention has reference to book covers, but more particularlyrefers to book covers which have a stiff back portion and flexible sidecovers, preferably of leather, that are hinged to the side edges of theback portion.

The object of the invention is to utilize a well known type of hingeelements that are secured in such manner to the parts of the cover, thatthe latter is exceedingly durable and attractive, while the side coversthemselves are opened and closed with the greatest facility.

Referring to the accompanying drawing Figure 1 is an interior view ofthe completed book cover with the side covers fully opened.

Figure 2 a section. at the line 22 of Figure 1.

Figure 3 a section at the line 3-3 of Figure 1'.

Figure 42 a detail elevation of one of the hinge elements, and

Figure 5 is a detail sectioned perspective of a modified form of backportion equipped with hinge elements.

Similar numerals of reference denote like parts in the several. figuresof the drawing.

1 is an outside back portion, preferably of leather, although it may beany suitable fabric or non-metallic material, 2 a metal plate,preferably concavo-convex in cross section although it may be straightin some instances, superimposed upon the inner face of the portion 1,and 3 are flexible strips of any suitable soft penetrable material, suchas fabric, leather or some kind of paper, which rest upon the upper faceof the plate 2 said strips beinig glued to the plate or not as occasionmay demand.

4: represents an elongated metal strip having extending from oppositeside e ges se ies Serial No. 654L398.

ofspaced fingers 5, 6, the fingers of one series being staggered withrespect to the fingers of the other series.

These fingers are bent around, the fingers 6 having their extremitiesclenched within the outer face of the leather portion 1, while thefingers 5 are bent so as to form alined eyes 7, the extremities of thesefingers being then clenched within the strips 3.

This clenching of these fingers holds the portion 1 and the metal plate2 firmly in their proper relative positions, as clearly shown in thedrawing.

A metal strip like that shown at Figure 4 and heretofore described hasits fingers bent and clenched into the edges of the cover portions 8 theshorter finger 6 being clenched into the outer faces of the covers,while the longer fingers 5 are bent so as to form alined eyes 9, theirextremities being then clenched into the inner faces of the covers.

These eyes 7 and 9 are then interengaged and the pintle 10 insertedtherethrough so as to complete the hinging of the covers. The ringstructure (not shown) is secured in position in the usual manner bymeans of the eyelets (only one shown) 11, the plate 2 being perforatedand having a countersunk portion 12 formed in its outer face toaccommodate the head of the eyelet.

Referring to Figure 5, there has been provided a leather back portion 13whose side edges are folded around the metal plate 2, these edges,denoted by the numeral 1 1-, being then turned down over and against theside edge portions of such plate.

When the hinged strip is positioned it is bent and clenched just as inthe manner described with respect to Figure 1.

It will, of course, be readily understood that no novelty whatever isclaimed for the particular form of hinged strip shown at Figure 4, sinceall that is aimed at in this application is the adaptation of this stripin a novel manner for the formation of the book cover referred to.

What is claimed is 1. The herein described improvement in book covers,which consists of a back portion comprising an elongated metal plate, afacing of non-metallic material on the back of said plate, non-metallicpenetrable material imposed on the inner face of said plate,

a metal strip having extending from opposite side edges series of spacedfingers, the fingers of one series being staggered with respect to thefingers of the other series, one series of fingers having theirextremities clenched into the non-metallic material on one face of themetal plate while the other series of fingers are bent to form alinedeyes that project from the side edges of said back portion and theirextremities then clenched into the nonmetallic material on the otherface of said metal plate, flexible non-metallic covers, metal.

strips having extending from opposite side edges series of spaced andstaggered fingers which are'clenched into the covers near the inneredges and on opposite faces thereof the fingers of one series being bentto form ali-ned eyes prior to clenching that project from the inneredgesof said covers, the eyes at the edges of the back portion and at theinner edges of the covers bein interengaged and alined toformcomplementary hinge elements, and pintles inserted within saidelements.

2. A book cover comprising a back portion consisting of a metal platefaced on both sides with a non-metallic pcnetrable material, alinedhinge eyes projecting from the side edges of said back portion formed bya series of oppositely projecting and staggered fingers one side ofwhich is bent around to form the eyes and with their extremitiesclinched into said material on one face of the plate, the other sidebeing bent around and clinched into said material on the other face ofsaid plate, whereby the latter is hehl in position, flexible side covershaving alined hinge eyes along their inner edges, the eyes of the backportion and side covers being interengaged, and a pintle insertedthrough said eyes.

In testimony whereof I aflix my signature hereto.

JOHN SCHADF.
